Struct Access

pub struct Access<'a, T, D = HasSelf<T>>
where
    T: 'static,
    D: HasData + ?Sized,
{ /* private fields */ }

Provides access to either store data (via the get method) or the store itself (via AsContext/AsContextMut), as well as the component instance to which the current host task belongs.

See Accessor::with for details.

Implementations

impl<'a, T, D> Access<'a, T, D>

where D: HasData + ?Sized, T: 'static,

pub fn data_mut(&mut self) -> &mut T

Get mutable access to the store data.

pub fn get(&mut self) -> <D as HasData>::Data<'_>

Get mutable access to the store data.

pub fn spawn( &mut self, task: impl AccessorTask<T, D, Result<(), Error>>, ) -> JoinHandle

where T: 'static,

Spawn a background task.

See Accessor::spawn for details.

pub fn instance(&self) -> Instance

Retrieve the component instance of the caller.

Trait Implementations

impl<'a, T, D> AsContext for Access<'a, T, D>

where D: HasData + ?Sized, T: 'static,

type Data = T

The host information associated with the Store, aka the T in Store<T>.

fn as_context(&self) -> StoreContext<'_, T>

Returns the store context that this type provides access to.

impl<'a, T, D> AsContextMut for Access<'a, T, D>

where D: HasData + ?Sized, T: 'static,

fn as_context_mut(&mut self) -> StoreContextMut<'_, T>

Returns the store context that this type provides access to.
